In the Mixed Reality Lab, this head-mounted system is part of a technology designed to create virtual humans that can walk directly up to a service member and try to intimidate them. The problem is that in order to be effective, the virtual human must look directly into the eyes of the service member. This is a very tricky problem, but Bolas' lab has come up with this system which has a projector on the helmet that sends out light that is then reflected back. In order to work, the system must know where the wearer is standing so that the virtual human's eyes are pointed directly at the wearer's.
